Subject: [PATCH 2/9] ARM: perf: add devicetree bindings for 11MPcore, A5, A7 and A15 PMUs
Date: Fri, 10 Aug 2012 18:36:28 +0100 [thread overview]
Message-ID: <1344620195-22372-3-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1344620195-22372-1-git-send-email-will.deacon@arm.com>
This patch adds separate devicetree bindings for 11MPcore and
Cortex-{A5,A7,A15} PMUs in preparation for improved devicetree parsing
in the ARM perf-event CPU PMU driver.
